Bradley's products sometimes call this design "Castle Otway Knot" or "Interlace Panel Design"; its bold central knotwork panel pops out like a piece of metalwork against the more subdued spiral border behind it.
This is the first in a series of diamond-and-bar designs that are available on greeting cards and other merchandise.
Here a circular knotwork panel becomes the central motif of another diamond-and-bar design. An intricate border frames the strong central panel.
In this third of the diamond-and-bar series we get four "gripping beast" eagles, composed of spirals and naturalistic heads and wings, in a zoomorphic panel standing out from the border designs behind.
